Hi,

I just want to make sure my interpretation of counting tests for CBCs is correct.  CLIA says

 

For complete blood counts, each measured individual analyte that is ordered and reported is counted separately.

So for example, if we did 100 CBCs, and we're counting WBC, RBC, Hgb, MCV, RDW, Plt count, Neut, lymph, mono, eos, and baso (11 tests) it's reported as 1100?

Thank you in advance.

Rachel

Hi Scott,

Billing is an entirely different matter than counting tests for CLIA.  Refer to page 9 of CMS form 116.  For hematology then, hematocrit and MCHC are not counted because they are calculated, not measured. Thanks,

Rachel

For annual test volume, you're counting the measured components of the CBC separately - WBC, RBC, PLT, Hgb, MCV - but the differential itself is one test. So one CBC is actually 6 tests. Calculated parameters like RDW don't count towards the total.
